Speed-sensitive Volume
Compensation (SVC)
The SVC mode controls the volume
based on vehicle speed. The faster
you go, the louder the audio volume
becomes. As you slow down, the
audio volume decreases.
The SVC has four modes; SVC OFF,
SVC LOW, SVC MID, and SVC
HIGH. Turn the selector knob to
adjust the setting to your liking. If
you feel the sound is too loud,
choose low. If you feel the sound is
too quiet, choose high.
This function is set to MID as the
default setting when the vehicle
leaves the factory.
